33
How much energy goes from one level of the pyramid to the next?
10%
34
What is the energy from each level that is not passed on to the next wasted on?
Movement, heat and chemical processes
35
What is an example of a chemical process?
Cellular respiration and body processes.
36
What can there not be 6 tropic levels of an energy pyramid?
Because there would not be enough energy for all the levels.
37
Where does the first level of the energy pyramid get its energy from (the producers)?
The sun
38
What is an example of a 1st order consumer?
Rabbit
39
What is an example of a species being introduced?
Rabbits They eat the grass They are competition for other animals so there is less food for they others
40
Predator prey relationship
The preying of one animal on others. One animals benefits to the injury of the other
41
What do competitors compete for?
The same resources, food, shelter and mates
43
Herbivores

44
What part of the body does cellular respiration occur?
In cells
45
Symbiotic relationship parasite/host
Organisms living together, depend on each other.
46
What are 2 examples of scavengers?
Hyenas and vultures
47
What is an example of a predator prey relationship?
Tiger and antelope
48
What is an example of competition?
When there is a shortage of rain = Less grass = Cows compete
49
What is an example of a parasitism relationship?
A tick on a cows fur Living off its blood It's causes damage to the cow However it can still survive
50
Parasitism
The relation between two different kinds of organisms in which one receives benefits from the other by causing damage to it, although not fatal damage.
51
What does ATP do?
Stores energy
52
Introduced species
A species that has been released in an ecosystem in which it does not occur naturally.
53
What are tropic levels?
The energy levels
54
What are examples of parasitism?
Worms and ticks
55
What do introduced animals and plants cause?
Disturbs natural food chains and webs
57
Omnivore
Eats both plants and animals
58
What are plant producers known as?
Photo - autotrophs
59
What is are two examples of decomposers?
Bacteria and fungi
60
Ecosystem
Made up of living (biotic) parts, such as communities of organisms, and non living (abiotic) parts, such as the physical surroundings.
64
What is an example of a producer?
Plants
76

107
Classification
The science of placing organisms into groups based on shared features
108

127
Intra species competition
Meme ears of the same species compete for eg. Mates
128
Exploitation
1 species benefits at the expense of an other
129
Biosphere
The narrow belt around the earth that contains all the living things
130
Biome
A broad life zone eg. Tropical, aquatic
131
Diurnal
Active during the day
132
Nocturnal
Active during the night
133
Crepuscular
Active during dawn & dusk
134
Niche
Describes the way of life of a species/population, in an ecosystem
135
Food chain
A series of links between different organisms in ecosystems based on feeding relationships
136
Ectoparasite
A parasite that live ON the host
137
Endoparasite
A parasite that lives IN its host
138
Mutualism
Both organisms in the relationship benefit eg. Lichen = fungi & algae
139
Commensalism
One organism benefits and the other does not but is not harmed eg. A spider building a web on a tree
140
Amensalism
One species is inhibited or killed and one is unaffected eg. A sapling growing under a mature tree
141
Food web
A series of interactive food chains
142
Organic molecules
Molecules with carbon, hydrogen and oxygen and is made by living things eg. Lipids, carbs, protein
143
Photoastroph
Use light energy to make organic molecules in the process called photosynthesis (Photo = light)
144
Chemoautotroph
Use energy from chemicals to make their own organic molecules. (Chemo-chemicals) (autotroph-self-feeder)
145
Biomass
The total dry weight of an organism.
146
Tropic level
Place in the food chain e.g. Produces first trophic levels.
147
Bioaccumulation/biomagnification
A nonbiodegradable substance accumulates in higher concentrations in a higher trophic levels.
148
Eutrophication
Nutrient pollution in waterways leads to Algal balloons. Algae and other plants die, decomposes thrive but use lots of oxygen. Fish die due to depleted oxygen levels. Accelerated ageing of waterways.
